ABSTRACT:
An apparatus for loading and storing elongate load members such as logs includes a base frame and two pairs of opposed extensible columns pivotally connected to the frame. The apparatus is carried between loading sites on a truck bed from which it can be loaded and unloaded by its extensible legs that retract within and extend from each column. The legs are hydraulic cylinders that also extend the columns to lift the load. Each pair of upright columns are connected by cables that support a load as the columns are extended. A vehicle bed can then be backed onto the frame between the columns to receive the load. Each column includes a fairlead that enables the cables to raise the load twice the distance the columns are raised, so that the columns need only be extended half the height of the vehicle bed.
